Mainline Cleaning

If a single drain in your home is sluggish, it is likely that you have a blockage somewhere in that drain’s piping. When all of the drains in your home are sluggish, though, there may be a blockage in the main sewer line. If so, you should call us immediately to perform a mainline cleaning.

Symptoms of Mainline Backups

The main line is the line that connects your home to the public sewer system. When sewer main line backups occur, they often cause the following problems:

  • Kitchen and bathroom sinks drain slowly
  • Standing water inside of the bathtub or shower
  • Toilets back up and may also back up into tubs
  • Washing machines and dishwashers fail to drain properly

What Causes Mainline Backups?

Main line stoppages are all too common. Stoppages can be caused by foreign objects entering the sewer line, old corroded cast iron piping, orange-burg piping, collapsed piping, tree roots, flushing of cotton products, offsets, and so much more. This is why it is important to not only get the immediate stoppage opened, but potentially get the line camera inspected once flow is restored. 

How to Resolve Sewer Main Line Backups

If you think you may have a mainline backup, you should contact us to perform a cleaning. We have several methods we use to perform mainline cleanings, including mechanical as well as hydraulic. We can clean the entire main line from your home to the public sewer system as well as the portion of the main line under your home. Once we complete the mainline cleaning, your drains will function the way they were meant to. We also have tools and equipment that allows us to fix any sewer line if drain cleaning just won’t cut it. 

How Often Do Main Lines Need to Be Cleaned?

In some cases, sewer main line backups occur as a one-time event because someone flushed an object that they shouldn’t have, such as a paper towel, feminine napkin or toy. When that occurs, the main line may only need to be cleaned one time to remove the object. However, other cases involving older sewer pipes that are corroded and deformed may need to be cleaned as often as every six months to prevent mainline backups from recurring.
